During CES Kodak was showing off a cool wireless printing app they will be releasing in March. The app will be limited to printing to Kodak printers but this is a big step for printer manufacturers to support BlackBerry printing. I asked them and they plan on supporting image printing so you can easily print out the pics you took on the go. If you need wireless printing now you can always use Remote Print.
Doug over at Inside BlackBerry got a video of the app in action as you can see below:
